ABSTRACT
The seroprevalence of porcine circovirus type 2 (PCV2) in the swine population of Trinidad and Tobago was studied, focusing on the association between the seroprevalence of the virus and each of four variables gender, age, group, farm size, and geographic location. Farms were classified as large (>1000 sows) or small (2 pigs to 250 sows); three age groups-nursery pigs (3 to 10 weeks, n=82), grower (11 to 22 weeks, n=107), and breeding animals(n=85) were studied. A multistage sampling design with non-proportional sampling between strata (farm sizes) was employed. A total of 274 serum samples were tested, collected from three large farms (n=109) and 109 randomly chosen small farms (n=165). Samples were tested using the PCV type 2 indirect fluorescent antibody test kit by VMRD (USA). Sixty-one percent of the farms tested were positive (2 large farms, 66 small farms). The overall seroprevalence of PCV2 was 62.0% (170/274) and after adjusting for non-proportional sampling between strata, was 70.3% ...
